digitalFAQ.com Forums [Archives] - Avisynth: Optimal script for avi DV source?

In my personal experience, I have found that Dialhot's AVI script works better for DV sources, with the addition of deinterlacing and the 60i to 24p function.

This is what I use, but am open to suggestions of something better!

Quote:

import ("C:\scripts\convert60ito24p.avs")
Sourcefile="D:\My Documents\My Videos\DV.avi"

avisource(Sourcefile)

#
# Great filter for adding the DV Time Stamp!!
#
#DVAutoTimeStamp(Sourcefile,20,450,360,-1,"Arial",44,$00FFFFFF,$00000000,86400,125,"MMMM dd, yyyy",1)
##

SmoothDeinterlace(tff=false, doublerate=true, blend=false)
convert60ito24p(2,0)

converttoyv12()
BlindPP(cpu=4)

Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)

GripCrop(544, 480, overscan=2, source_anamorphic=false)
GripSize(resizer="LanczosResize")
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
#Blockbuster(method="noise",detail_min=1,detail_ma x=10,variance=0.3,seed=5623)#only in worst case
GripBorders()
converttorgb()
# END

And the Convert60ito24p function:

Quote:

function convert60ito24p (clip video, int mode, int offset)
{
work = assumefieldbased(video)

out =(mode==3) ? interleave(
\selectevery(
\layer(trim(work, 1, 0),
\layer(work, trim(work, 2, 0), "fast"),
\"fast"), 5, 0 + offset),
\selectevery(
\layer(
\layer(work, trim(work, 3, 0),"fast"),
\layer(trim(work, 2, 0), trim(work, 1, 0),"fast"),
\level = 170), 5, 2 + offset)) :

\ (mode==2) ? interleave(
\selectevery(
\layer(trim(work, 1, 0),
\layer(work, trim(work, 2, 0), "fast"),
\"fast"), 5, 0 + offset),
\selectevery(
\layer(work, trim(work, 1, 0), "fast"), 5, 3 + offset)) :

\ (mode==1) ? interleave(
\selectevery(trim(work, 1, 0), 5, 0 + offset),
\selectevery(layer(work, trim(work, 1, 0), "fast"), 5, 3 + offset)) :

\ (mode==0) ? selectevery(work, 5, 1 + offset, 4 + offset) : work

assumeframebased(out)
}

# usage:
# import (convert60ito24p.avs)
# loadplugin(your 60fps deinterlacer like dgbob or tomsbob)
# xxxsource("clip")
# your60fpsdeinterlacer()
# convert60ito24p(2,0)

# mode - parameter:
#------------------
# 0 uses simple 24 out of 60 selection -> jerky motion
#
# A B C D E F G H I J K L M N O P Q R <- input sequence
# | | | | | | | <- | = direct copy
# 1 2 3 4 5 6 7 <- resulting output sequence
#
# 1 introduces a blending of every other frame from its nearest neighbors
#
# A B C D E F G H I J K L M N O P Q R <- input sequence
# | \ / | \ / | \ / | <- | = direct copy ; \ / = 50:50 blending
# 1 2 3 4 5 6 7 <- resulting output sequence
#
# this mode delivers a non-jerky motion and should be used with shutter speeds below 1/60sec!
# ie. 1/120 or shorter
#
# 2 uses blening on every frame like this:
#
# A B C D E F G H I J K L M N O P Q R <- input sequence
# \|/ \ / \|/ \ / \|/ \ / \|/ <- \|/ = 25:50:25 blending ; \ / = 50:50 blending
# 1 2 3 4 5 6 7 <- resulting output sequence
#
# mode 2 is ideal for shutter speed of 1/60 sec
# since it simulates very close the 24p (1/24sec) motion blur
# and thus giving a really smooth 24p - motion
# as a positive side-effect, this mode reduces noise and nearly comletely
# eliminates remained line flickering of the deinterlacing!
#
# every other number given to mode delivers the the input directly to the output (60fps)

# offset - parameter:
#--------------------
# here you can apply a offset for selecting the 2 out of 5 frames - pattern.
